destination MAC addresses.

authenticated destination MAC addresses.
ntkonly: Forwards only unicast frames with authenticated destination MAC addresses.
Usage guidelines
The NTK feature checks the destination MAC addresses in outbound frames. This feature allows
frames to be sent only to devices passing authentication, preventing illegal devices from intercepting
network traffic.

packets only to devices passing authentication.
